SDL3 is a set of C libraries for doing cross platform gamedev stuff. It abstract over platform APIs for things like window creation/management, input handling, audio etc.
Not even close, Proton is a translation layer from Win32 API to whatever works similar for Linux, SDL just gives a higher level API of lower level stuff, like instead of using Xorg/Wayland directly, you get a nicer cross platform API that does the job well

So kind of like proton, except for multiple platforms and in the source code instead?
